+/**
+ * Checks if `predicate` returns truthy for **all** elements of `collection`.
+ * The predicate is bound to `thisArg` and invoked with three arguments;
+ * (value, index|key, collection).
+ *
+ * If a property name is provided for `predicate` the created "_.property"
+ * style callback returns the property value of the given element.
+ *
+ * If an object is provided for `predicate` the created "_.matches" style
+ * callback returns `true` for elements that have the properties of the given
+ * object, else `false`.
+ *
+ * @static
+ * @memberOf _
+ * @alias all
+ * @category Collection
+ * @param {Array|Object|string} collection The collection to iterate over.
+ * @param {Function|Object|string} [predicate=_.identity] The function invoked
+ *  per iteration. If a property name or object is provided it is used to
+ *  create a "_.property" or "_.matches" style callback respectively.
+ * @param {*} [thisArg] The `this` binding of `predicate`.
+ * @returns {boolean} Returns `true` if all elements pass the predicate check,
+ *  else `false`.
+ * @example
+ *
+ * _.every([true, 1, null, 'yes']);
+ * // => false
+ *
+ * var users = [
+ *   { 'user': 'barney', 'age': 36 },
+ *   { 'user': 'fred',   'age': 40 }
+ * ];
+ *
+ * // using the "_.property" callback shorthand
+ * _.every(users, 'age');
+ * // => true
+ *
+ * // using the "_.matches" callback shorthand
+ * _.every(users, { 'age': 36 });
+ * // => false
